SHUTTLE.

Application led April 10,

shuttles and involves certainimprovements in the construction 'of theA threading eye whereby to provide for tensioning the thread and'to prevent ballooning or dethreading.

My invention consists' in the novel construction and combination of parts described and illustrated in the accom anying speci-l particularly in the .appended claims.

- Figure I is a partial plan view of the threading end of a'shuttle in accordance with my invention; i

. Fig. Hijs a section 0n the line 11i-'111,

eye removed.

. Fig. V is a 'section on the line Vf-VfFig. IV, and

l VView vof the tensioning.

I have indicated at 1 a hand threading shuttle' of standard type havingthe usual threading passages 2 and-,3 andthreading Set within the eye 4' isa bushing comprising tubular end sections 5 and 6 connected ,by a central web 7 an'd slotted along their underface as indicated at 8. The bushing is positioned within the eyeby means of an attaching tongue-9 which is bent, across 'the outer end 4ofthe section 5 and is adapted forv penetra'tve lodgmentin the w'ood of 'the shuttle.l

Across the inner end of the section 5a tensioning tongue-10 is bcnt down-from the web portion 7 of the bushing-and vcooperateswith a tensioning'post 11 whichis driven vertically from above into the .eye and intersects the bushing adjacent said tonguel l0', the

bushing being cleared away as indicated at l2 to accommodate the post l1. Thel ten-f sioning post 11 may be a simplespike having a pointedpenctrating end 13 and a rounded head. portion '14. The wood at the Spccincationot Letters Patent.

'Shuaie throat is' veaicaiiy slotted asyindifffcated at'15 -to receive the post 11 which isf inv effect keyed in said slots 15.v vThe head"- 14 hasa tensioning. eye 16 opening laterally into the threading'passage 2 as .indicated at- 17. The thread Tj from the bobbin enters said eye and is' drawn over thev lower-wall 18 thereof, which thus acts as a tensioning bar,`

and from said `bar 18 runs 'underthe'vten Sioningtongue 10 of'thesbushingmd but. Y

through'the end section 5 thereof; By varying the position of the post 11 relat'iv'eto the'4 bushing, the tension on the'threa'd may changed as desired. The portion 19 of the head l4. overlying" the v'eye 16 landspaced from the tensioning tongue 18 by the lateral kerf 17 ac tsfa's a .guard to prevent ballooning 'of the thread during the run of 'the' shuttle',` and'pgreferfi ably has its upper surface vdeveloped on a-'.` curve as shown, to facilitate the entrance 'o f the thread' into the laterally openedl eye.. 16.

In assembling, the eye piece 6' is lodged 'in theshuttle-ey'e 4 with its attaching' lin-gen!)4 embedded in the woodot' theshut'tle and its j i tensioningr Vtongue 10 disposed vacross the shuttle eye. The post 8 is their driven ver'- tically through tlieshuttle eye from'above to position its tensioningtongue18-above and in a directiontransverse'to the direc'-` tion ofthe tongue 10.

AVarious modifications .in tlie'constructior.

and operation of my device may obviously be resorted to if within thelimits'ofthe ap ended claims. V at I `therefore claim and l 1. Ina shuttle, 4the combination iivitli 'aA tensioning element disposed transversely-to the axis of the shuttle eye and'i'inder which the thread runs5 of an overlying tensioning" desire to sei element disposed parallel to thelaxi's ofthe shuttle eye' andv overI whichthe thread riins` 2. In a shuttle, the combination Vwithja tensioning element disposed `transversely -to the axis of the shuttle eyeand under which the thread runs. of an overlying tensioning element disposed parallel to the vaiiii's ofthelos shuttle eye and over which the threadrunsand a guard'spaced frornjand overlying s'a-i I' last named tensioning element.

3. In a shuttle. an eye piece having .a tensioning bar disposed transversely .to the axis thereof, and under which-the thread riins,x and a post having a tensioning bar disposedv lic horizontally above said firstLna-med tensioning bar and spaced therefrom and over which the thread runs to said first-named tensioning bar.

4. In a shuttle, a tubular eye piece havlng avtensioning bar disposed transversely to the axis thereof, and under which the thread i a threading passage leading thereto, a bush-v ing in said eye provided with a tensioning element, and a post driven into the shuttle from above said threading eye and having a laterally` slotted head providing a tensioning eye disposed above and spaced from said tensioning element of the bushing.

6. A tensioning element for a shuttle eye consisting of a member adapted to be driven into the shuttle from above the shuttle eye and having a. slotted head providing a tensioning element,

7. A tensioningelement for a shuttle eye consisting of a member adapted to be driven into the shutttle from above the shuttle eye and having a tensioning eye.

8. A tensioning element for a shuttle eye consisting of a member adapted to be driven into the shuttle from above the shuttle eye and a tensioning bar and a guard overlying said bar to prevent ballooning of the thread running over said bar. 9. In a shuttle, an eye-piece having a tensioning element, under which the thread runs and a tensioning element over which the thread runs disposed above and in a direction transverse to the direction of said first-.named tensioning element.

10. In "a' shuttle, an eye-piece having a tensioning element under which the thread runs, a tensioning'lelement disposed above and spaced from said first named tensioning element, over which the thread runs, and a guard spaced from and overlying said second-named tensioning element. an effective to prevent ballooning of the. thread running over said second named tensioning element.

11. `In a shuttle, the combination with a tensioning element disposed horizontally of the shuttle eye and under which the thread runs, of a member set vertically of the shuttle eye and having between its ends a tensioning element disposed above said first named tensioning element and over which the thread runs to' said first named tensioning element.

l2. In a shuttle, an eye piece having a horizontally disposed tensioning element under which the thread runs, and a horizontally disposed tensioning element fixed in the shuttle above and in spaced relationto said first-named tensioning element and over which the thread runs to said first-named tensioning element, said tensioning elements extendingsubstantially at rlght angles t()y slotted portion between its ends providing I a'tensioning element over which the thread runs.

14. A tensioning element for a shuttle eye, rcomprising a pointed member adapted to be driven into the shuttle and having a tensioning portion between its ends over which the thread runs and a guard ,spaced from and overlying said tensioning portion and effective to prevent ballooning of the thread running over said tensioning portion. In testimony whereof I affix my signature in presence of two witnesses.-
